木材受潮后吸收水分，水分一般进入细胞的空腔，细胞壁开始膨胀，细胞的膨胀

The wood absorbs water after being wet. The water generally enters the cavity of the cell, and the cell wall begins to expand. The expansion rate and degree of expansion of the cell are different, and the wood will have different shape changes, deformation, cracking, and warpage.

Wood absorbs water after moisture, moisture generally enters the cell cavity, the cell wall begins to expand, the expansion rate and expansion degree of the cell is different, wood will produce different shape changes, deformation, cracking, warping and so on are the result of changes.

Wood absorbs moisture after being damped. Water generally enters into the cell cavity, and the cell wall begins to expand. Different expansion rate and expansion degree of the cell result in different shape changes of the wood, such as deformation, cracking and warpage.<br>
